CF11 licensing - Virtual Machine - vCPU and CPU

Hello,

I read some questions here forum, considerations of the number of processors (virtual or not).

My understanding:

- Each license CF11 STD supports 02 CPUs

- My virtual machine is configured with 4 vCPU's (no core's). In this case, I am considering for licensing "4 CPUs."

My scenario:

- Virtual machine with 04 vCPU.

- This virtual machine, run a site in Coldfusion and another site in .NET.

- I would like to license only 02 CPUs because my site in Coldfusion needs few processing resources.

My question:

1) If I buy 01 license Coldfusion 11 Standard (02 CPU´s), I can install on a server with 04 CPU´s and configure ColdFusion to use only 02 CPUs? Is this possible?

Thank you very much.
